IQ-Series Electric Actuator Specifications
 
Model IQ IQT IQM/IQML
Description Provides intelligent commu-nication options and a multi-lingual display. The IQ range offers multi- and quarter-turn isolating/regulating duty. For quarter-turn applications the IQT is designed for direct drive, and can be mounted at any operating angle. The rugged construction is double-sealed to prevent water and dust ingress even during site wiring. The IQM range combines Rotork's motor and gearing technology developed over 40 years, with the latest electronic techniques used in IQ to produce the IQM modulating range.
Torque Range Torque range 14 to 3,000 Nm (10 to 2,200 lbf-ft) direct drive (multi-turn only). Higher torques when com-bined with IS or IB gearbox, up to 40,800 Nm (30,000 lbf-ft). Quarter-turn when com-bined with IW gearbox up to 250,000 Nm (185,000 lbf-ft). Torque ranges 50 to 2,000 Nm (36 to 1,475 lbf-ft). Torque range 12 to 550 Nm (9 to 400 lbf-ft). Thrust range with linear output IQML 16 kN to 55 kN (3,500 to 5,600 lbf).

Model A/AWT ROM IW
Description The A / AWT range com-bines the qualities of a robust electric motor and a well proven simple mech-anical drive.

Total environ-mental sealing to IP68 allows the inclusion of integral motor starter and control electronics.
Building on the simple specification of the ROM / RBM range, Rotork now off-ers a more complete control solution with the introduction of the new ROMpak.

ROMpak introduces: Local controls for ease of oper-ation; Dual local indicators - mechanical and LED; Phase rotation correction for ease of installation; Options including: bluetooth non-instrusive configuration, bus communication and Folomatic/CPT, datalogger.
The IW range of quadrant wormgear valve operators features a removable sleeve to facilitate bore and keyway machining.

This sleeve can be rotated in steps to faci-litate mounting to the valve.
